Description

Technical Field

[0001] This utility model belongs to the field of mining fire protection technology and relates to a mining fire protection device. Background Technology

[0002] Fire hazards exist in the operation of various equipment underground, and water-based fire extinguishing systems are usually installed. In current technology, water-based fire extinguishing systems use a series of fire sensors to monitor the fire situation. After the fire sensors collect fire information, they upload it to the control center. The control center processes the data and coordinates and controls the system to extinguish the fire at the point of ignition.

[0003] This method has the advantages of low cost and stable operation of the fire protection system. However, the control center processes a large amount of data, which can lead to system crashes and slow response. Furthermore, if the control center malfunctions, it may paralyze the entire fire protection system. Utility Model Content

[0004] To achieve the above-mentioned technical objectives, this utility model provides a mine fire-fighting device. The mine fire-fighting device can realize distributed data processing and control functions, and the water pressure for fire-fighting is relatively stable within the fire-fighting system.

[0005] The aforementioned mine fire-fighting device includes: a pump station, a main pipe, branch pipes, an intelligent valve, and multiple fire sprinklers. The pump station includes a first controller. The main pipe is connected to the output end of the pump station. Multiple branch pipes are connected to the main pipe. Each branch pipe is equipped with an intelligent valve. Multiple fire sprinklers are installed at locations in the mine with potential fire hazards, and each fire sprinkler is connected to the output end of a branch pipe.

[0006] The intelligent valve includes a fire monitoring sensor and a second controller. The fire monitoring sensor is installed on one side of the corresponding fire sprinkler head and is configured to monitor the fire situation within the spray range of the fire sprinkler head. The fire monitoring sensor is electrically connected to the second controller. The second controller is configured to connect the corresponding branch pipe after receiving the fire information uploaded by the fire monitoring sensor. The second controller is also electrically connected to the first controller, which is configured to control the water output of the pump station based on the information uploaded by the second controller.

[0007] Preferably, the pumping station includes: a power mechanism, a fire pump, a water storage tank, and a valve assembly. The power mechanism includes an output shaft. The input end of the fire pump is coaxially and fixedly connected to the output shaft of the power mechanism. The lower outlet of the water storage tank is connected to the inlet of the fire pump. The valve assembly includes multiple electric valves, each connected to the outlet of the fire pump, and the other end of each electric valve is connected to the main pipe.

[0008] Preferably, the first controller is electrically connected to the power mechanism and the valve group. The first controller is configured to receive signals uploaded by the second controller, analyze the required fire water volume and the main pipe that needs to supply fire water based on the signals, and control the output power of the power mechanism to correspond to the opening and closing of the electric valve.

[0009] Preferably, the intelligent valve further includes an electric ball valve, which is electrically connected to the second controller.

[0010] Preferably, the mine fire-fighting device further includes a compensation unit, and the compensation unit is provided on the main pipe between the branch pipe and the pump station.

[0011] The compensation unit includes a tank and a compensator. The tank is connected to the main pipe, and the space inside the tank is in communication with the main pipe. The fire-fighting water from the pump station flows through the main pipe and the tank before being directed to the branch pipe. The compensator is an elastic block structure, located inside the tank. The compensator has a tendency to adjust its volume according to the water pressure inside the tank, thereby stabilizing the water pressure within the tank.

[0012] Preferably, the power mechanism includes a variable frequency motor and a reducer, wherein the output shaft of the variable frequency motor is coaxially and fixedly connected to the input shaft of the reducer, and the output shaft of the reducer is the output shaft of the power mechanism.

[0013] The beneficial effects of this utility model are as follows:

[0014] First, the first controller of this utility model only receives signals uploaded by the second controller to control the pump station, without processing the data collected by the fire monitoring sensors, thus reducing the computational requirements of the first controller. The second controller can autonomously perform fire extinguishing operations according to the on-site fire situation. Therefore, even if the first controller malfunctions, the pump station can still be manually controlled to ensure the normal operation of the fire protection system.

[0015] Second, when the fire sprinkler of this utility model is running, there may be sudden changes in water pressure in the main pipe and branch pipe due to the delayed response of the first controller. The compensation unit can make the water pressure in the main pipe and branch pipe relatively stable, eliminate the water pressure changes in the main pipe and branch pipe caused by the sudden operation of the fire sprinkler, and provide a guarantee for the normal operation of the fire protection system.

[0025] The present invention will be described in detail below through specific embodiments:

[0026] like Figures 1 to 5As shown, a mine fire-fighting device includes: a pump station 1, a main pipe 2, branch pipes 3, an intelligent valve 4, and multiple fire sprinklers 5. The pump station 1 includes a first controller. The main pipe 2 is connected to the output end of the pump station 1. The multiple branch pipes 3 are connected to the main pipe 2. Each branch pipe 3 is equipped with an intelligent valve 4. The multiple fire sprinklers 5 are installed at locations with fire hazards underground, and each fire sprinkler 5 is connected to the output end of a branch pipe 3.

[0027] The intelligent valve 4 includes a fire monitoring sensor 41 and a second controller 42. The fire monitoring sensor 41 is installed on one side of the corresponding fire sprinkler head 5 and is configured to monitor the fire situation within the spray range of the fire sprinkler head 5. The fire monitoring sensor 41 is electrically connected to the second controller 42. The second controller 42 is configured to connect the corresponding branch pipe 3 after receiving the fire information uploaded by the fire monitoring sensor 41. The second controller 42 is also electrically connected to the first controller, which is configured to control the water output of the pump station 1 according to the information uploaded by the second controller 42.

[0028] In some embodiments, pump station 1 is located away from the underground working face. Multiple main pipes 2 are connected to pump station 1 and laid to the corresponding working face. Each main pipe 2 is connected to multiple branch pipes 3 at the working face location. Fire sprinklers 5 are installed at the ends of the branch pipes 3, and each branch pipe 3 is equipped with a smart valve 4. It is understood that the main pipes 2 and branch pipes 3 can be laid to the top of the tunnel. The fire monitoring sensor 41 of the smart valve 4 is installed on one side of the corresponding fire sprinkler 5 to monitor whether there is a fire at the corresponding location within the spray range of the fire sprinkler 5. If a fire is found, a fire signal is uploaded to the second controller 42. The second controller 42 can connect the corresponding branch pipe 3 and upload a signal to the first controller. The first controller starts pump station 1 or increases the operating power of pump station 1 according to the signal so that pump station 1 can provide sufficient fire water to the fire sprinklers 5.

[0029] In this embodiment, the fire monitoring sensor 41 may be a flame monitoring sensor and / or an infrared sensor and / or a smoke monitoring sensor.

[0030] The first controller can be a PLC, and the second controller 42 can include a microcontroller.

[0031] Preferably, the pump station 1 includes: a power mechanism 11, a fire pump 12, a water storage tank 13, and a valve assembly 14. The power mechanism 11 includes an output shaft. The input end of the fire pump 12 is coaxially and fixedly connected to the output shaft of the power mechanism 11. The lower outlet of the water storage tank 13 is connected to the inlet of the fire pump 12. The valve assembly 14 includes multiple electric valves, each connected to the outlet of the fire pump 12, and the other end of each electric valve is connected to the main pipe 2.

[0032] Preferably, the first controller is electrically connected to the power mechanism 11 and the valve group 14. The first controller is configured to receive the signal uploaded by the second controller 42, analyze the required fire water volume and the main pipe 2 that needs to supply fire water according to the signal, and control the output power of the power mechanism 11 to correspond to the opening and closing of the electric valve.

[0033] Preferably, the intelligent valve 4 further includes an electric ball valve 43, which is electrically connected to the second controller 42.

[0034] Preferably, the mine fire-fighting device further includes a compensation unit 6, and the compensation unit 6 is provided on the main pipe 2 between the branch pipe 3 and the pump station 1.

[0035] The compensation unit 6 includes a tank 61 and a compensator 62. The tank 61 is connected to the main pipe 2, and the space inside the tank 61 is in communication with the main pipe 2. The fire-fighting water from the pump station 1 is directed to the branch pipe 3 after passing through the main pipe 2 and the tank 61. The compensator 62 is an elastic block structure, disposed inside the tank 61. The compensator 62 has a tendency to adjust its volume according to the water pressure inside the tank 61, thereby stabilizing the water pressure inside the tank 61.

[0036] In some embodiments, the tank 61 may be a cylindrical tank 61 with an inlet and an outlet on its side wall. The main pipe 2 includes: a first main pipe 21 disposed between the tank 61 and the pump station 1, and a second main pipe 22 disposed between the tank 61 and the fire sprinkler head 5. One end of the first main pipe 21 is connected to the pump station 1, and the other end is connected to the inlet of the tank 61; one end of the second main pipe 22 is connected to the outlet of the tank 61, and the other end is connected to each branch pipe 3.

[0037] A compensator 62 is installed inside the tank 61. The compensator 62 can be a rubber spherical cavity structure. When one or more fire sprinklers 5 on the main pipe 2 are activated, the first controller receives a signal and begins to control the operation of the pump station 1. This may cause the operation of the pump station 1 to lag, resulting in a sudden drop in water pressure in the main pipe 2. The compensator 62 can eliminate the sudden drop in water pressure. Furthermore, when the output power of the pump station 1 increases, the compensator 62 can recover under the action of water pressure.

[0038] It should be noted that a tubular filter screen 63 is installed on the inner wall of the tank 61 at the water outlet to prevent the compensator 62 from clogging the water outlet.

[0039] Preferably, the power mechanism 11 includes a variable frequency motor and a reducer, wherein the output shaft of the variable frequency motor is coaxially and fixedly connected to the input shaft of the reducer, and the output shaft of the reducer is the output shaft of the power mechanism 11.
